control thathas a reciprocable operating slide member. a Another object isthe provision of fraud-preventing' dogs cooperable With a coin slide member to prevent the operation of Y'the device-by means of captive coins or coins having attached thereto' an extremely thin metal yor like ribbon by means'of which the coincan be Withdrawn for repeated use after the slide has been operated.

Still another object is the 'provision of a device of the class described in which a coin', after it has been moved by the slide member Va predetermined distance, cannotbe retracted because of the automatic positioning of stopping and latching dogs engageable with the coin and the slidemember in a particular'manner so asfto prevent return movement.` f f f Yet another object is the provision of cooperating fraud-preventing dogs one of which is oper- 'ated by a coin to cam another into position to latch the` slide member positively against return movement. f Y -if Still" another object is the provision of a standard frame structure adapted to operate vwith slides having coin pockets or openingsfof differentsizes for reception of coins of different denominations,l together With auxiliary attachment means therefor and useful to the same end. f

S. Patent 2,082,037 -of whchI am one of the patentees and in which some of the basic structural'features of the slideframeA and depositing orgejecting Amechanism', k shown herein, p arenset forth in detail, referencebeing had to said patent for a more detailed discussion of such basic features. I

InL general, a 'form' of coin slide with ywhich my presentpinvention can `befused advantageously,` is shown inFigflgherein, and includesa main frame lor guide-having a `-veriiinal mountingplate. or wall I0 anda horizontalshelfj or-.bed plate II which extends fat right .anglesin bothvv directions from the mounting WallfIIJ. -Provided along `the lopposite longitudinal edges of thev main frame shelf-or-bedplate I. `Iare opposite guide grooves I2 in which is slidably fitted acoin slide member I 3 forreciprocable movement therein. v In theslide member I3'are a spaced apart vcoin pocket and sightopening I4and I4 respectively (lligs..4 and 5) onenear the front and one near the rear of the .slide member. yJoining these `pockets I4 is-alongitudinally extensive slot or 'channel lI 5 (Figi 5) .which extends rearwardly beyond the rear orinner opening'll' asat I5". in Idotted linesin Fig.v 1.V for purposes laterto. appear, I Similarly, ythe slot- I5 (Fig. 1) has a short forwardextension I5. beyond the front 'pocket 4Ill'. Adjoiningthis'forward slotextension I5 is av short, depending, j inwardly, slanting, grooved Ilug-lli. l

rThe purpose of thisslot extension` I5, and groovedp'art of the lug .I6V is to receive certain fraud-preventing dogs `I'I' and I8','both of which function independently, so to speak, of 'the novel the invention,'but which are nevertheless'described to avoid confusion. These latter dogs I'I and' I8are mounted above the slide member I3 on the top'sideof the bed plate II.

" Provided -in the frame just behind or to the left vof theinountingI plate Il), below the nose of a dog Il (Fig. 2), is adr'op-cut hole 9 for undersized coins. The slideqin the present instance being designed to receive've-cent pieces, zand acnec'ent piece Would,under ordinary circumstances, vdrop out'through hole 9. f

, Ther-inner portion ofthe shelf lor bedv plate II nasa coin kdischarge opening or Well I9, to the right-of which `(Fig. 2) is anadjoining shelf or 5.5. ledgell', formed integrally: withv the bedl plate,

onto which a deposited coin tends to move by its own weight out of the front pocket I4 of slide member I3 when the latter is moved inwardly. By continued inward movement of the slide I3, a coin 2| on shelf member 20 will be pushed by the depending grooved lug I6 past certain nonretracting dogs, later to be described, for ultimate movement into the well I9.

Mounted for reciprocable sliding movement below the well |9 on shelf or bed plate II is an auxiliary or second ejecting slide 22 normally urged toward the right or front and the mounting plate or wall I by means of a spring 23 so as to position a coin pocket or aperture 24, formed in the auxiliary slide, below the bottom of well I9 to receive a coin from the latter. Below the ejecting slide coin pocket 24 when the latter is in its normal position there is a small pan 25 attached by screws 26 to the bottom offrame II and serving to hold the ejecting slide member in place and also to prevent a coin, such as 2|' (Fig. 4), from fallingV out of the pocket or aperture 24 in the ejecting slide member, except when the latter is shifted fully to the left so as to carry the coin past the rear edge of the pan, thus permitting the coin to be ejected or cleared from the slide mechanism. l

Shifting of the auxiliary or second ejecting slide member 22 i-s effected by means of an upstanding pin 21 (Figs. 2 and 4) which projects upward into the rearward extension I of the longitudinal slot I5 in the main slide member and is there engaged by a shoulder notch 28 cut into the slide member in the rear channel extension I5' (Figs. 4 and 5). ber yI3 moves inwardly to its full stroke position, andl when the ejecting Aslide member 22 is thus moved, a coin 2| (Fig. 4) resting in the rearmost coin pocket 24 in the auxiliary slide member 2'2 and on the pan 25, will be pushed beyond the rear (left) edge of the latter to gravitate into a suitable receptacle.

Mechanism including a full stroke dog 29 engageable with edgewise teeth 29 in slide member I3 (Figs. 1 and'5), prevents retrograde movement of the slide member while a coin remains in thecoin pocket II4 and permits retrograde movement only when the slide member I3 has been moved to position'a coin below the opening I4'. It may be remarked that the purpose of the rear sight opening I 4 in main slide I 3 is to permit the viewing of a deposited coin through the lsight opening I9 overlying the well I9 (Figs. 1 and 2).

v However, there is a limited amount of retrograde or return movement of the slide member, madepossible by inherent structural peculiarities or clearances' of the moving parts of the mechanism, and this feature has an important bearing on the special fraud-preventing dogs provided in the present invention.

Mounted conveniently on the lower rear bed plate II is a trio of dogs 36, 3|, 32. The first of these, or the latching dog 36, is pvotally mounted as vat 33 near the right-hand edge of the slide member |3, as seen in Figs. 2 to 6, so that its nose portion 34 extends upwardly through a slot in the bottom of the bed plate II for bearingengagement with the bottom of slide member I3. The slide member is .provided with an edgewise notch 35 (Figs. 5 and 6) into which the nose 34 of dog 30 will be moved under certain conditions when the slide is vpushed into a predetermined position, corresponding to that seen in Fig. 4, where a coin 2| has been moved between the nose 36 of the When the slide memmiddle or coin-stopping dog 3| and a lug 46, to be described.

Stopping dog 3| and the outer or second stopping dog 32 (which acts to block attempted retraction of coins by shims, wires, etc., once the coin has passed these dogs) are mounted on a common stud or pin 3'|, and these dogs are provided with spring means 40, 4 I, respectively, operable to urge the noses 36 and 38 of the same toward the slide member I3. The middle dog 3|, however, has a widened or oversize pivot or pin hole 39 (Figs. 2, 4, 6) which makes it possible for theA dog to shift transversely, especially in a Vertical direction, on its axial mounting without rocking movement of the nose 36 or tail 43, and thus, cooperably with its biasing spring 40, to shift radially or transversely to accommodate the dog for operation with coins of various thickness, so that the basic fraud-preventive mechanism will operate reliably whether the coin be a onecent piece or a five-cent piece, since it is contemplated that the testing chute may, by simple change, be made to test either denomination of com.

At this juncture, it may be explained that the outer one 32 of the two stopping dogs 3|, 32, has its nose 38 disposed for movement upwardly in a direction into the front 'coin pocket I4 (when the latter passes toward the shelf 20 and well I9), the nose 38 being spaced in a direction across the pocket opening transversely of the slide member away from the middle or main stopping dog 3 I, so that both of the latter dogs may engage the rear or trailing peripheral edge portions of the coin as the latter is moved inwardly past said dogs, whereby to prevent fraudulent retraction of the coin, it being noted that the middle dog 3| is disposed slightly in advance (toward the left, Figs. 6 and 8) of the dog 32'.

At the rearward edge (Figs. 4 and 5) of the coin pocket or hole I4 is a small depending pin 50 which will engage the forward or advancing edge of the coin 2| upon an attempted retraction of slide, before the latter has made its full inward stroke (as in the situation of Fig. 4, for instance),

- the pin urging the coin against the spaced noses 36 or 38 of the pair of stopping dogs 3| and 32 respectively, provided the coin has been advanced past these dogs, but not far enough to move into the well I9, or even under the latter circumstances, if the coin is captive, when an attempt is made to retract the same by means of a shim or wire along with the slide member.

In addition, there is a fixed depending lug 46 attached to the bed plate I I or a part thereon to overlie the nose 36 of the middle dog. This lug is somewhat like the lug 46 in the aforementioned patent, and serves cooperably with the nose 36 of the middle dog 3|, to pinch the coin and tilt it upwardly so that pin 50 may surely engage the leading edge of the coin upon attempted retracttion as aforesaid after the coin has moved onto the nose 36 of the middle dog 3|.

The latching dog 36 has a lateral ear or lug 42 (Figs. 4 and 6) which extends above the tail or end 43 of the middle stopping dog 3|, and when the latter dog is pivoted by engagement with a coin, tail 43 will bear against lug 42 and pivot dog 30 and the nose 34 thereof will enter the edgewise notch 35 formed in slide member I3 at a point along its edge so that the nose 34 will, in synchronism with the inward movement of the slide member I3, engage the notch 35 therein as soon as the coin engages the nose 36 of stopping dog 3| and remains in the notch 35 during such engagement.- Y t is thereafter impossibleto cause a withdrawalof the coinV slide |3 which willfb'e latched by the nose 34 because the dog 3|-`is-im movable due to the presence of the coin'vbetween the nose 36 and lug`46 (Fig. 4) thus pivoting `(or transversely' shifting)` the dog ori-pin 31 and causing the tail 43 thereof4 to bear against the lateral lug 42 of the latching dog`30." 'I'he harder the retractive pull, the more iirmly does the latching dog 30 become wedged as a result,` of 'the cainaction of the stopping dog- 3|. This latter feature is of especialimportance in those at'-v tempts at fraudulent operation wherein 'a thin metalribbon is attached to "an otherwise genuine coin" and the'latterA deposited until the slide vis operated, l' and thereafterwithdrawn rbyr the rib` bon'. Such an 'endeavor isl utterly 'frustrated by the coactionof the' middle stopping dog 3| and the latching dog 3|), and 4even where coins or tokens of different thickness lare used, legitimately or fraudulently, the provision' of the en"- larged pivot hole 39'a`ssures the faithful operation of the-dogs to this end.

Once the slide member is'moved tofcomplete inward position with the coinI beneath the sight opening I4' the-coin will have passedr beyond engagementwith the latching dog 30 andthe stopping dog 3| to permit the latter two dogs to again assume normal positionVv prior to withdrawal of the slide member |3.` "U v 1 Attention: is calledto the importance of the transverse or lateralhshiftability of the middle stoppingY dog 3| in view fof-the fact that the nose 34l of the latching "dogf30 -must ride against the underside of the `lslide memberexcept when it is raised into the notch 35, andjthus there is suiiicient yieldability on the part'ff'tlie vmiddlestop'- ping dog 3| ."by virtue of'its t and on the part of the latchin ydog 30 inso far as its operative association 42;-43 4with thefmid- 'dle stoppingdog 3| yis concerned, to permit adequate freedorrrofy movement of `both 'dogs without danger of interlocking, particularly when the coin is tilted fin the pocketby action of stopping degss land, sz and ldie iuge, in iegitimate eser; ation. ,A

Because of the foregoing particular arrangement of the dogs, andespci'allyftheprovision of means for shifting 'the stopping dog 3| ltransversely of its' pivotal axis, the'inventin will-insure against fraudulent operatiorcf-the kind specified, even thought'he coins "used vary vin thickness or diameter, and it "adapts they basic operating "mecl'ianisrn` to proper use with coins "of several denominations, such as nickels or pennies.
